Mr. Tucker - Although I have done but little as a contributor to your valuable periodical, I have been a " constant reader " of it for many a day, and I have been much amused with the papers upon the much vexed strawberry question. Whether in England we get the same quantity of fruit that Mr. Longworth does from the same number of plants, I will not pretend to say; but as the size and flavor of our strawberries leave nothing to be desired, and as they are grown in very large quantities for the London market, I think it may not be uninteresting to many of your subscribers to know something about the mode of growing them there. But the more special reason which induces me to trouble you with this pnper, arises from the remarks, which I have seen in many of the numbers of the Horticulturist, upon the qualities of several of the English varieties of the strawberry, and which Show that as they are at present grown in this country, they arc far from realizing the beautifully luscious and aromatic taste that several of my American friends, who have eaten them in London, agree with me in attributing to them.

The difference in this particular is so important as of course to render them here valueless; and it doubtless arises from the difference of climate, which we all know influences materially many fruits even between England and the north of France; consequently we need not be surprised at the effects produced, where the meteorological chances and the range of them, are so much more sudden and extensive as they are in this country, when compared with England. One of the material differences which operates prejudicially upon this fruit in this climate, is the much greater rapidity of the change from the intense cold of winter to the heat of summer. The strawberry, when roused from its dormant state in spring, requires but moderate warmth to develope its flower stalk and bloom, and again, but a slight addition to that heat lo swell and ripen its fruit. Then, again,when it is in bloom and the fruit is just setting, it requires an ample supply of water; and this, in England, it generally gets, and the size of the fruit is very decidedly less if the spring there happens to be dry and hotter than in ordinary years.

I can see no reason, however, why gentlemen in this country, who have greenhouses and other plant structures, should not grow strawberries early in the year in pots, and produce fruits equally fine in every particular with that which is grown in the same way in England; because, in those circumstances, the heat of the house can be regulated so as to avoid the prejudicial natural effects which here operate upon them under open air cultivation. I propose, therefore, to give you the system which I pursued as an amateur when in England, (and it is the same as is usually adopted by the gardeners round London, who force this fruit for the early spring market) and by which I had always fruit fully ripe by the second or third week in April.

I must first make, however, a remark upon the varieties of the stawberry to be used. Upon the whole, no variety is found so useful, all things considered, for the earliest crop of fruit as the true Kean's Seedling; (for there are many round London not true;) this will bear more heat in forcing without loss of flavor, or in quantity, than any other. The usual plan adopted by growers of moderate extent, is either to confine themselves to this variety, and Myatt's British Queen, or to grow their principal stock of these two varieties. There is no question about it, that in England no variety can compare to the British Queen, either for size, flavor, or product; but it will not submit to be rapidly forced, and in the open ground, it is impatient of too much rain, which will injure its flavor and also cause it to burst when just ripe. The flavor of this variety there, is exactly like a strawberry and pine apple combined; and as regards size, I have seen twelve strawberries exhibited which weighed one pound avordupoise; and I will undertake to say that a person walking through London, the end of June or beginning of July, may, without difficulty, at any fruit store, find this variety averaging from 16 to 20 berries to the pound.

I believe it to be perfectly possible to grow it here in the same perfection, and simply by trying the following plan which (as before stated) is that pursued in England:

In the month of August, small pots measuring two or three inches diameter are filled with good loam, and placed upon or sunk to their rims in a strawberry plantation; a runner is placed on the top of each pot, and a stone put upon it to keep it there. These are watered occasionally, if dry weather, and in six weeks the plant will have filled this small pot with its roots. It is then cut off from the mother plant and immediately repotted, of course without breaking the ball of roots, into a pot six inches diameter, in good rich loam, not sandy, if it can be had, (for in that I have seen the best fruit grown) and if not, then into a compost of the best garden soil that can be got, and old hot-bed manure, half and half. The pots are then placed in a situation where they get the morning sun only, and being kept moderately waterd they remain until the end of the year.

About the first week in January, these pots are brought into the green-house or forcing house, and placed upon a shelf close to the glass. This is essential: success must not be expected, unless they are kept up at the top of the house, and feeders, or pans for water, are placed under each. At first, they mnst not be subjected to much heat; only keep a moderate temperature at night, letting the sun increase it by day; and at first, also, the supply of water must be moderate, not giving enough to allow it to stand in the pans; but as the plants begin to throw up their blooming stalks, the supply of water may be increased, and the temperature also, but very gradually. When the plants are just coming into bloom, they should be syringed over well every morning, but as soon as the bloom pips begin to open, the syringing should be discontinued until all the fruit is set. As soon as this has taken place, syringing may be resumed while the fruit is swelling, and during this period of growth the feeders should be kept well supplied with water. When the first berries begin to color, the syringe is dispensed with, and the supply of water should not be so profuse, although care must be taken that the plants do not suffer for want of it, and the heat while ripening may be slightly increased.

The degree of heat throughout the growth, after the first month, is not of so much consequence, as is the maintenance of a gradual development of the energies of the plant, by avoiding a rapid increase of temperature at any period, for that will usually be fatal to the result.

It is a common thing for these forced plants, when they have yielded their crop of fruit in the month of April, to be put in a cold frame for a fortnight, and then in May, turned out of the pots into a freshly dug piece of ground, where at the end of July, they give a moderate crop of fruit, thus giving two crops before the plant is quite twelve months old. Then from their layers a renewal of the plants takes place, and the same round of culture is resumed for the following year.

Such is the present course of strawberry forcing pursued around London; and yet, I remember twenty years ago, or thereabouts, it was usual, and thought necessary to grow the plants two years in pots, before they were fit to be placed in the forcing house.

I do not think it possible to grow the British Queen in perfection in this country out of doors; but I see no reason why it should not be so in houses, or in flued pits or frames.
